本文整理了PHP汉字拼音转换和公历农历转换两个功能类文件，非常实用。比如我们查找通讯录可以通过联系人姓名的拼音首字母来查询，可以通过首字母来导航大数据量，可以通过转换拼音来做网站优化等。公农历转化一般用在日历日程安排的项目中，方便农历的节日提醒等等。
1、PHP汉字转拼音
Pinyin.class.php类文件可以将大多数汉字转换成汉语拼音，当然也有个别生僻字不能转换，如果你想转换所有的汉字拼音的话，可能需要再配合一个汉字字库来实现，使用该类文件就基本能满足你的项目需求了。用法：
复制代码 代码如下:
require_once("Pinyin.class.php");
$pinyin = new Pinyin();
$str = '好好学习天天向上';
echo $pinyin->strtopin($str);
执行后输出：hao hao xue xi tian tian xiang shang。
如果只是想输出汉字首字母则使用：
复制代码 代码如下:
echo $pinyin->strtopin($str,1);
执行后输出：hhxxttxs。
Pinyin.class.php 源码：
